I’m no expert, but I’d seek legal advice from an attorney to learn your rights and responsibilities. After a dog injures someone or another dog, the owner is then on notice their dog is dangerous. This may then expose you to liability, if the there is a subsequent injury. And, you might check your homeowner’s policy for coverage if you keep a dangerous dog on your property. There are multiple ways this could be very risky for you financially. I’d find out the laws as they apply in your state. There may also be local ordinances about dog’s who have injured others.

If your husband has dementia, logic and reasoning may not be something he is capable of using. His focus may be only on what he wants and not the consequences. The dog could injure your husband or you. Plus, the welfare of the dog is at stake. Animal welfare officials might find your husband’s treatment of the dog unacceptable. I understand why you are concerned about the situation on many levels.

Trying to keep a loved one happy is always the goal, but I learned that when someone has dementia, they may not be capable of being happy and content, regardless of their situation. Sorry you are going through this. I hope you can find a solution soon.
